HOW IT WORKS

Three steps to a better interview

01

Choose your track & target

Coding or system design. Pick your company and level (SDE-1 through Staff), and we calibrate the session to that bar.

02

Interview with Alex

Alex drives the session end to end — clarifying questions, approach or architecture, trade-offs, coding or whiteboarding, and live evaluation.

03

Get your signal

Instant feedback with a hiring signal and dimension-by-dimension scoring. Know exactly where you stand against the bar.

TARGETED PREP

Calibrated to your target role

Coding problems are drawn from real interviews at your target company in the last 6 months. System design sessions are judged against the bar for your target level.

FEATURES

Everything a real interview has

Real AI Interviewer

Alex asks probing questions, validates your approach, challenges your complexity analysis and design trade-offs — just like a real FAANG engineer would.

Live Code Execution

Your code runs against hidden test cases automatically. Alex sees the output instantly and probes deeper if anything fails.

Voice + Video

Think out loud the way you would in a real interview. Full voice and video interview experience — coming soon.

Company-targeted

Select Google, Meta, Amazon, Apple, or Microsoft. Problems are pulled from real interviews at that company in the past 6 months — not generic LeetCode sets.

Deep Feedback

Every session ends with a full report. 12-dimension scoring for coding; weighted parameter scores and level readiness for system design.

System Design Whiteboard

Architect on an interactive canvas while you talk. Alex sees your diagram live and probes what's missing.

5 Languages

JavaScript, Python, Java, C++, or TypeScript. Pick what you're comfortable with and code in your own style.

FAQ

Common questions

What is InterviewSkool?

InterviewSkool is an AI-powered mock interview platform that simulates real FAANG-style coding and system design interviews. An AI interviewer named Alex walks you through every stage — problem clarification, approach design, complexity analysis, coding, and hidden test suite evaluation for coding; requirements, architecture, and deep dives on a whiteboard for system design — and issues a hiring signal at the end.

Does InterviewSkool support system design interviews?

Yes. Pick a problem (or go random) and a level — SDE-2, SDE-3, or Staff Engineer. You design on an interactive whiteboard while talking through requirements, architecture, and deep dives with Alex, and get a 0–100 score with per-parameter feedback and level readiness.

How does the AI interviewer work?

Alex is an AI interviewer. It asks probing clarifying questions, validates your approach, challenges your complexity analysis, and adapts based on your answers — just like a real FAANG engineer would.

Which companies does InterviewSkool prepare you for?

Google, Meta, Amazon, Apple, Microsoft, and many more. Problems are sourced from real interviews at those companies and calibrated to the difficulty bar for SDE-1, SDE-2, and SDE-3+ levels.

What programming languages can I use?

JavaScript, Python, Java, C++, or TypeScript. Pick whatever you are most comfortable with.

How is InterviewSkool different from LeetCode?

LeetCode is a problem bank — you solve problems alone and get a pass/fail. InterviewSkool simulates the actual interview conversation: Alex asks questions, challenges your reasoning, and evaluates how you communicate, not just whether your code passes.

What is a hiring signal?

The recommendation a real interviewer would make after your session: Strong Yes, Yes, Lean Yes, or No for coding interviews. InterviewSkool computes yours from 12 dimensions including code correctness, communication, DSA knowledge, and optimization mindset. System design interviews get their own signal — Strong hire, Acceptable, Needs work, or Not ready — from weighted parameter scores.

How much does InterviewSkool cost?

InterviewSkool offers simple pay-per-use pricing: ₹399 for 1 interview (valid 30 days), ₹1500 for 5 interviews (valid 180 days), or ₹2500/month for 10 interviews. No subscriptions, no hidden fees.
